Tim,
I believe Vagabond, SJM, and I all share a belief that anonymity on the internet is a wise policy. There are identity thieves, flame masters, and internet psycho-stalkers who can/could make your life miserable if they desired. In addition, prominent people within the game are just a target sometimes for confrontational posters. People who truly love and respect the game (like Vagabond and SJM) will measure a person's character by the ideas expressed in their posts, not by their name or notoriety.
Having said all of that, I can tell you that I fully intended to NEVER reveal my identity to anyone who posts regularly on the internet. My intention originally in attending the WPBA tournaments was to speak to NO ONE except a player/friend of mine. I have basically totally failed in my original intention because (MUCH to my surprise) almost every single AZB'er that I have met has been a true pool fanatic like myself, and I have very much enjoyed their company. Zeeder, Woody, SJM, Christy D, ChefJeff, WallyinCincy, ZimsRack, Sarah R., Melissa H., Jennifer B., Vagabond are ALL very nice people, great pool fans; and I'm way ahead of the game having made their acquaintance (apologies to anyone I've left out); and my tournament experiences have definitely been better as a result.
